SLOTTED MEMBER FOR OORSE'I CLASPS.

Specification of Letters Patent.

Application filed December 28, 1917. Serial No. 209,260.

To all whom it may concern:

Be it known that I, HERMAN A. KELLER, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented certain new and use ful Improvements in Slotted Members forCorset-Clasps, of which the following is a specification.

The present invention relates to the construction of the slotted memberwhich forms a part of the clasp used for connecting together thesections of a corset.

The principal objects of the invention are to provide a member of thecharacter specified which is cheap and simple in construction, and whichis capable of application to a corset stay in a quick and ready manner,

- reducing the number of operations now generally employed for attachingsuch a member to a corset, and thus reducing the cost of production ofthe corset.

A further object of the invention is to so form the clasp member as topresent a series of smooth surfaces when it is aflixed to the corsetbody.

The invention further consists in the features of construction andcombination of parts hereinafter described and claimed.

In the drawings:

Figure 1 is an elevation showing a plurality of the clasp members of thepresent invention attached to a corset stay;

Fig. 2, a perspective of one of said clasp members;

Fig. 3, a section through a clasp member and a portion of a stay,showing the clasp member in position on the stay and before it issecured to the stay; and

Fig. 4, a View similar to Fig. 3, showing the clasp member secured tothe stay.

In the art to which the present invention relates, so far as I am aware,it has been customary to apply the slotted member of a corset clasp tothe corset stay by inserting into the clasp membera pin which is upsetso as to form a rivet head for connecting it to the clasp member; andthe depending portion of these pins is inserted through suitable holesin the stay and the lowerends are then upset to form a rivet connectionbetween the stay and clasp member. This results in quite a number ofoperations being necessary in securing these clasp members in place; andthe riveted ends of the slotted pins are liable to present roughsurfaces, which are undesirable.

In the present invention, I produce, by a die drawing process, aplurallty of hollow depending studs 5, which in the construction shownare two in number, although this may be varied as desired. These aredrawn from the metal at what may be termed the inner end 6 of a claspmember 7. The outer end 8 of this clasp member is formed with the usualbutton-hole slot 9 for engagement with the headed stud 10, forming thecompanion portion of the clasp. The metal from which the slotted memberis formed is of light construction, and thus the walls of the dependingstuds 5 are of light, thin metal. These studs are closed at their lowerend by a wall 11, and this lower end, when upset, forms a rivet head 12,which is of a smooth surface, whereby a firm and efficient connection isformed between the stay and clasp member.

Patented Oct. 21, 1919.

In securin this clasp member to the stay, 7

the only operations are the insertion of the hollow studs through theopenings 13 in the stay and the upsetting of the ends of the studs toform the rivet heads. Thus, after the slotted member is once formed,these two operations are all that is required to secure it to the stay;whereas in the prior art of which I am aware, the slotted member mustfirst be formed, the pins must be formed, these pins inserted withinholes in the slotted member, then upset on one end to secure them to themember, then the depending portions of the pins inserted through theopenings in the stay and the lower ends of the pins upset to secure themto the stays. 7

It will thus be apparent that several steps in the manufacturingoperation are saved by the use of the present invention.

As will be observed from Figs. 3 and at, this construction of slottedclasp member is such that no rough surfaces are produced by securing itto the stay. The studs being drawn from the body of the clasp memberpresent a smooth edge at the outside face of the clasp member, and beingof a light, hollow construction, can be readily and easily upset, andwill form a smooth surfaced rivet head. As shown in the construction, anembossed surface 14 is formed in the clasp member merely for the purposeof reinforcing the thin metal so that it will not bend.

I claim: 2. A slotted clasp member for corsets com- 10 1. A slot-tedclasp member for corsets comprising a thin sheet metal plate having aprisin a thin sheet metal plate having a keyhole slot therein and tWohollow studs keyhole slot therein and two hollow studs punched therefromWithin the perimeter 5 punched therefrom Within the perimeter thereofand depending from the rear face thereof and depending from the rearface thereof, the metal being embossed along 15 thereof, the metal beingembossed along lines lines beginning in proximity to said studsextending in the general direction of the and continued along the sidesof said slot. keyhole slot along opposite sides thereof.
